[PATCH 4.9 82/83] builddeb: fix cross-building to arm64 producing host-arch debs

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adam Borowski <kilobyte@xxxxxxxxxx>

commit 152b695d74376bfe55cd2a6265ccc75b0d39dd19 upstream.

Both Debian and kernel archs are "arm64" but UTS_MACHINE and gcc say
"aarch64".  Recognizing just the latter should be enough but let's
accept both in case something regresses again or an user sets
UTS_MACHINE=arm64.

Regressed in cfa88c7: arm64: Set UTS_MACHINE in the Makefile.
